lie it-kunwn thattly'lno lnvto Cam )N E, engineer, a eitizenof the Swiss lie mblie, residing at Charlottenlnn'g, near Ber in, (in f l asanenstrasse, Germany, have invented i eet-tnin new andtztmdul Improvements in or Relating-to Elastic Tires for Wheels; 2 ad I; do hereby declare the following to be a full, l clear, and exae't deseri itia'n ot' the invention. such as will enable ot iers skilled in the art to which itnppertnitts tonmke. andusc the Sillll.

This inventionrelates to elastic tires at tlni t ype wherein two ormore ittextensible spread.- ing tings are disposedwithina tubular easing of rubber, leather ext-similar material.

Aeeortlittg to lhis im'ention the tubular casing is pressml fronrthe outsideagainst tlte interior oh the tire by means of an desired present! device. This forein oi t e easing towards the interior can be ellieeted from the of the wheel or even from; the sides, this being done according tothis. invention by means of rings of: variablediameter, which force the correspomlingftortions of the casing inm-reeesses. t formed imthe inextenaible rings.

As already stated, the wheel tire cont prises, one, two. or more -euitably shaped inextensible rin s a b' .poset'l within a tuburubber; leatherer similar matertal. I t In the construction shown inFigs 1-4 the inner ring 6 is provided with a Press d directed towards the interior of the cash 5 into whit-lithe under portion e of the elastic easing c, immediatety )eneatb it is forced by the extensible ring f whieh nets on the tilt-- dt-t'side of the easing from the outside in the manner shown in Fig. 3. The forcing in is ell'et-led, as can be seen in Fig. 3, bytlte two ends of the extensible ring f being pressed fasee-rl-ained the and tn what manner the same 1 formed I declar that what Lehnm ts:-

After the tire has been stretehee in this 60 manner, it is, as shown by wa of exam do in Fi 2, pushed into the ritn I' from which one tango has been removed whereupon the, flange it's attached, by bolts It' or by other known means. 65 In the t onstrnction shown in Figs. (PS the pressure on, the elastie easing 0 is effected tn such a manner that the outer or tread portion of. the same is fOI'C-Qdg y a device 1 against a recess m in the outerspreuding ring a the recess being directed towards the center of the wheel. This device is in the present ease, not pressed outwards, but. eompressed inwards and held in the desired position by :1. plate It. 7b The devices illustrated. are deserilwd merely by wny of example. The ressing of the elastic easing into the hnl ow Space formed by rceessing the spreading rings which it surrounds can be effected in any desired manner.
